WRENCH.

SPECIFICATION forming part of Letters Patent No. 701,929, dated June 10, 1 902.

I Application filed March 17, 1902. Serial No. 98,508. (No model.)

To aZZ whom it may concern.-

Be it known that I, FRANCIS C. PEABODY, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.

My invention relates to improvements in wrenches, its object being, to provide improved actuating means for the movable jaw of the Wrench. V

To this end myinvention consists in the features of construction and combination hereinafter particularly. described and claimed, 1 In theaccompanyingdrawings,formingpart of this specification, Figure 1 is a side view of my improved wrench. Fig. 2 is a similar View with one side of the casing. for the sliding jaw removed. a Fig. 3 isa similar view with the actuating mechanism released- Fig. 4 is a section on line mm of Fig. 2; and'Figs. 5, 6, and 7 are details of a lever,-link, and dog, respectively, constituting the cooperating parts of the actuating mechanism. 1

In the drawings, A represents the main bar' of the wrench, formed with a downwardly-projecting jaw 2, and teeth ,3 upon its inner side.

4 represents a slidable jaw supported intermediate of the casing-plates B. Having pivotal support 5 in the casing at the rear of the slidable jaw is a dog 6,.pro-vided with teeth 7, adapted to en gagewith the teeth 3. The pivoted end of the dog6 isprovided with a down-. wardly-projecting flange 8, to which is pivoteda link 9, the opposite end of the link being provided with an opening 10 to receive the eccentric 11 of the lever 12. The lever 12 has pivotal support 13 in the casing and is provided with an upwardly-projecting cam 14. The outer end of the lever 12is preferably provided with a finger-opening l5.

In operation, ,theslidable jaw being moved to the desired position upon the wrench-bar and the lever 12 turned into -the position shown in Fig. 2, thecarn; 14, carried by the lever 12, willpress;against themnder side of the dog 6, holding said dog in engagement with the teeth of the wrench-bar. As the ingposition.

,lever 12 is' turned into the position shown in plied to a monkey-wrench, I do not confine myself to such use andmayemploy the same in connection'with anywrench havinga movable jaw. 'Ifalso do not restrict myself to the A use of a single link 9, but may duplicate the same and i other wise modify the construction without-departing from my invention,

the scope of which-isdefine'd in the claims.-

I claim-+ f 1. In a wrench of the class described, the

combination with a bar and fixed'jaw, of a jaw slidable upon said bar, a supporting-casing for said slidable jaw, a dog pivoted in said" casing, a lever, a linkfconnection between saiddog and lever, and a cam carried by said lever, and adapted to be turned into engage ment with said dog to hold the same in lock= 2. Ina wrench of the-class described, the combinatiomwith a bar andjaw, of "a slidable jaw carried by said-bar, a dog pivotally supported in connection with. said slidable jaw, a pivotally-supported lever, a link connection between said dog and lever, and a cam carried by said lever and adapted to be turned against said dog to actuate the same.

" 3. In a wrench of the class described, the

combination witha bar and fixed jaw, of a slidable jaw supported by said bar, a dog pivotally supported in connection with said slidable jaw, a lever, an eccentric carried by said lever, a link connecting said eccentric and dog, and a cam carried by said lever, as and I for the purpose set forth.

4. In a wrench of the class described-the combination with a bar and fiit'edjajw; of

slidable jaw, a supporting-casing carriedgby' said bar, a dog pivotally supported in said tric carried by said lever, a link connecting said eccentric and dog, and a camcarried by the pivoted end of said lever, as and for the purpose set forth.
